An NYPD spokesperson told the outlet Hadid called authorities after the man, named Ryan S. Perez, was allegedly seen standing near her apartment building on Thursday night. He was arrested around 9:35 p.m. after Hadid claimed Perez had sent “numerous unwanted threatening messages” to her via social media between December 17, 2017, and Feb. 7.

Perez was then charged with aggravated harassment and stalking. The investigation is still ongoing, and it's unclear if he remains in custody, the spokesperson said.

Despite the incident, Hadid was later spotted at a birthday dinner for friend Samuel Krost, and shared video of the night on her Instagram stories.
